I had heard that Rubino Pros were great for brakeless riding from adamkell on here, and then I bought a set. When they came in, adam said that they were different (perhaps newer) than the ones that he had used. I've had them on for about a month now, and I don't do a terrible amount of skidding or skipping, and I'm down to the threads already. I would go with the Vredesteins just because I am extremely unsatisfied with the Rubinos. They're a real pain to mount and dismount on the rims too.
Great Backstreet Boys reference, by the way.
